So I am trying to organize this Group Buy and we have already gotten a few people to sign up from different forums with some dependent on the final price. This is from the XClutch Rep: "We're also open to a group buy if you think you have enough numbers to do so." I am thinking if we get to at least 10 people then we might have something, 20 people I'm sure would mean a stellar price for all of us.

Let me know if you are interested, I'll throw you on the list! ...

Background
Bought the car in 2012 and went full bolt ons over the next few years. Last year is when I decided to take it the next step further and go single turbo. Now at this point I had no intention on this being a dedicated drag car. It was meant to see a track day every...

Almost a year and a half ago I finally found the e92 335i I had been relentlessly searching for. It was in Ga (I live in Fl), but that didn't matter to me. 6spd MT black with coral red interior sounded too good to be true. 30 minutes from leaving the dealership I had already experienced my first taste of N54 life.

I know I posted about a month or so ago about going single. I was sure that was what I wanted to do until Pure decided they would say f*ck you to everyone else and released their turbos with a cast manifold much cheaper... So cheap in fact that it`s sitting at around exactly half the price of what a Docrace 6266 BB kit would have cost me.

I'm on dual cm7s with 50/50 mix but who knows in the future after I start working with a tuner. E85 is not an option, and a plate style probably isn't an...

I'm having a heck of a time deciding on what to use for fueling. I have the pumps in place so that's not an issue. I'm not sold on the expensive intake manifolds and I want my best bang for the buck. That being said if an aftermarket intake manifold is the best way to go then so be it. Power goals are 750-800. I'm currently only running a 6266 so my expectations are in place. I want some headroom for a...

The base is billet and so is the plenum base but the dome is pressed sheet metal.

Its going to be around half the weight of whats available atm most likely 12 to 13 pounds without the pi rail and injectors.

It will be fully tested against the fabfactory manifold and hopefully will have independent testing done early in january

The car has transformed into a BRUTAL razor blade like machine. Throttle response and power to pavement is almost instantaneous. I was taken aback and worried at first from the increase in NVH. But after driving for a few miles...it did begin to settle and the NVH is decreasing incrementally. I like this brutality...

I see different turbo companies bragging about how fast spool and torque with X brand turbos. The majority of people are on stock rods so kind of pointless it seems. Meaning on stock internals, many of us dont need the crazy fast spool as many advertise and can go with XX brand instead that spools slower for a happier engine.
